I got a started Knight & Hale starter turkey kit that came with a slate pot call, push pin call, crow call and a learn to call CD. It also came with a piece of chalk that I assume is for the push pin call. So my question is, how do I chalk the push pin call? The instructions didn't mention the chalk at all.

I assume I need to chalk the little triangler wood striker, or that paddle that attaches to the pin or both....
